hey ya. seem to be stuck in a 120-150k average dps slump. I have my rotation down, dots on procs, flay fillers. currently pushing the mastery due to the 2p T16, any tips, or suggestions would be much appreciated.

Logs would indeed make it a lot easier, but just looking over your gear, I see a few mistakes; your haste is waaay low, you dont wanna be around just 10k should go for at least the DP breakpoint at 14873, your mastery is way high same goes for your hit, cut em both, and get as close to hit cap and push more stats into haste and you should see an increase. Thats about what I can do without any logs at hand to go through.
